The TP9 is rather infamous in Hollywood. I see it pop up quite often in TV shows and movies as a bad guy gun. It was originally designed by Steyr in the late 80s as the TMP but the design was sold to B&T in 2001 and turned into the MP9. The TP9 is the civilian version. It looks like a European version of a Mac 11. I can’t imagine shooting this like a handgun would be very effective. However with a vertical grip and stock, as it was intended, would be much more stable and usable. The photo is by @atlanticfirearms.
